Procedure:
1. Connect the circuit on breadboard as shown in figure.
2. Supply 220V,50Hz sinusoidal signal across lamp load.
3. Connect at PMMC ammeter in series with auto transformer.
4. Place the hall sensor close to the wire.
5. By varying the load note down the actual and measured current values and calculate
the error percentage.
